Despite reports in July to the same effect, Molyneux is quoted today saying, "It is [done] as of 7pm last night." He continued, "We are now officially gold. It's released to manufacturing. Fable is absolutely finished and done and dusted."
If the game really, truly is complete, it should make its announced release date of October 21 in North America and October 24 for Europe.
Sounds good, hopefully the release might be earlier than we all thought.
